i' l v This; invention relates to loom. shnttles-and trol uncoiling `engage-nient typ'ewheren lacontrol member engages. thefyarnas it is the shuttle. v z .y y lt hes been proposed heretofore to lcontrol thefdelveryof thread vor lillngfrom the nnwonndf from. the thread package'withi-nshuttle bythe use of bristles or brushes withinj the bobbin chainbenlwhich engage the jnnwindingviilling..y The brushes or bristles,

however, frequently become.. entangled with the 'I filling and cause brealrage-` It has been further proposed to secure tothe side wall of fabric lextending theffnllflength of the E fill-ing ,barrier or bobbin which f rnay, in a nieaslire, at. least, control delivery of the filling from the shuttle.

' l.eis-the filling is withdrawn from the shnt.

tlerduring weavingfitj tendsftojV balloon in the. bobbin chamber and snch ballooning is generallyeinphasized near the; tip end of the bobbin .or llli-ngjcarrier andv often becomes serioiisly objectionable. f

One of` the objects .of the-present inventionisto` provide a lilling uncoiling control member securedgto a-.fwall `of ythe. bobbin chamber-with abow or bend, inherently tiere ible and adapted for engagement withv the 11n-winding filling near thetip portion of' the bobbin as the filling is withdrawn troni the,shuttle/during weaving. Morespeciiieally st-atedfthe' filling 'n.ncoicli'ng control. inem- .ber has itsends secured. to the san-1e wall. of r the bobbi-n chamber at points separated a distance less than thestraight length of the Y iilling nncoil-ingy controlineniben with the result that abow or bendis .formed in said ynn ei1f-1 l;)er, which is. caused to. -projgect inwardly of vthebobbin chamber and-engage the un- 'Y lcoiling llin-g, to check itsfball'ooning tend- ,encyandyetyield sufficiently toa permit the F510' o f onek good-forni thereof.`
